100-Watt High Pressure Sodium HID Light Bulb - E26 Medium Base - Clear - 2000K Warm Yellow Light - 9500 Lumens - 24,000 Hours

Radiant Warm Yellow Light 

The 100-Watt High Pressure Sodium (HPS) bulb emits a distinct 2000 Kelvin warm yellow glow, commonly used in industrial lighting, parking lots, security fixtures, and roadway lighting. While this technology has been a reliable choice for decades, HPS bulbs require frequent maintenance, have poor color rendering, and are less efficient than modern LED alternatives. 

90 Lumens Per Watt (lm/W) Efficiency 

This 100-Watt HPS bulb produces 9,000 lumens, achieving approximately 90 lm/W. While once considered a high-efficiency lighting solution, LED technology now delivers 80-150 lm/W, providing brighter illumination at a lower operating cost. 

Ballast Compatibility & Replacement Considerations 

This bulb requires an ANSI Code S54 ballast for proper operation. However, HPS ballasts degrade over time, leading to: 

• Reduced light output and efficiency 

• Flickering or slow warm-up times 

• Expensive ballast replacements 

If you’re experiencing frequent failures or rising maintenance costs, it may be time to consider a ballast-free LED retrofit, which eliminates the need for a ballast entirely. 

A Smarter, More Efficient Alternative 

If you’re replacing a burned-out HPS bulb, now is the perfect time to upgrade to LED. Here’s why: 

✔ Higher Energy Savings – Use less power without sacrificing brightness. 

✔ Longer Lifespan – LEDs last 3-5 times longer, reducing maintenance. 

✔ Instant-On Performance – No warm-up time or flickering. 

✔ Eliminate Ballast Failures – Retrofit LEDs bypass the ballast, so you never have to replace another ballast again. 

✔ Better Light Quality – LEDs offer improved visibility, whiter light, and better color accuracy, making spaces safer and more visually appealing.
